A long bus ride
Why do you feel tired after a long bus ride?
The bus was constantly shaking, making people drowsy.
Because the carriage is sealed.
The concentration of carbon dioxide in a closed carriage is relatively high.
The load on the waist muscles when sitting is 30% higher than when standing.
After sitting still for two hours, the blood return rate in the legs decreased by 40%.
If you sit for too long, your legs may not be able to move.
Next time take a bus, open the window to ventilate and stand up and twist your waist every 50 minutes.
There are service areas on the motorway where you can walk around and stretch your body.
坐长途大巴为何感觉累？
因为车厢是密闭的。
密闭车厢二氧化碳浓度比较高。
坐姿的腰部肌肉负荷比站立时高30%。
静坐两小时后，腿部血液回流速度下降40%。
如果你坐久了，腿可能动不了。
下次坐车要开窗通风，每五十分钟站起来扭扭腰。
高速公路上有服务区，你可以在那里走走，伸展一下身体。
